If militant Islam now restricted itself to open battle as it did in it's beginning it would have no chance against the West. But it has found other mechanisms to advance it's cause: the lust of the left for political power and the submissive nature of its religious opponents who have placed themselves under the protection of the very temporal law the left despises and ignores when it has the power to do so. But In SF demographic projections are that it will become a white majority city within 20 years due to high property values built on tech and finance and if they do not decide to destroy themselves because of their white privilege the city may very well end up like Monaco,a very un PC police state dedicated to the protection of its rich inhabitants, where the only Muslims are wealthy and not given to law breaking because the cops and their rulers are without mercy and intolerant. Perhaps this will not happen but Islam will have a hard time as will any religion where the statisticians of science and money are powerful. However Don's predictions could easily become manifest in Minnesota or other places where the left dominates by vote and public largess is powerful.
